Nonreciprocal Mac network issue #2 - 07/24/10 10:51 PM
Since a few months I'm having a networking problem in which I can no longer connect (either wired or wireless) to a MacBook Pro from the other Macs on the home network, but a connection works just fine when it is made from the MBP to the others. This onesidedness wasn't always the case, as things worked OK once I had fixed a basic issue about a year and a half ago (Nonreciprocal Mac network listings), but since this somewhat different problem appeared my troubleshooting hasn't yielded a solution yet.
The link above describes the network in some detail, and this is still valid; the only difference is that the Macs now run Leopard except for one MB on Snow Leopard. I checked the current Network settings (including IP# and subnet mask) and they look OK; sharing is enabled everywhere. To be sure, I disabled sharing on the MBP, then re-enabled it, but this didn't change things.
The problem manifests itself in that the MBP is listed in the various (Go>) Network windows, but selecting it never goes anywhere until the attempt times out ('Connection Failed'). Interestingly, the MBP is the only Mac also represented as a PC server, but this option is nonfunctional.
Using 'Connect to Server' with the appropriate IP address won't work either, and returns the error message 'You cannot connect to this server because it cannot be found on the network. Try again later or try a different URL.'
From the other Macs' point of view the MBP behaves as if it were sleeping, but it isn't. Any guess(es) as to what I'm missing here?
